It was hot and humid at the Miami Masters Sunday and the heat was simply too much for one ballgirl, who looked dazed and confused on the court. Grigor Dimitrov saw what was going on and swooped in for the rescue. Sadly, Dimitrov lost to Japan's Key Nishikori in straight sets. But he's still a hero people. Also, he's dating Maria Sharapova soooooo life is good for him!
